Diagnostic Procedure with Diagnostic Trouble Code (DTC)
ENGINE (DIAGNOSTICS)
83 CHECK HARNESS BETWEEN ECM AND
FUEL INJECTOR CONNECTOR.
Measure the resistance between the ECM con-
nector and engine ground.
Connector & terminal
#1 (E158) No. 12 — Engine ground:
#1 (E158) No. 11 — Engine ground:
#2 (E158) No. 24 — Engine ground:
#2 (E158) No. 23 — Engine ground:
#3 (E158) No. 36 — Engine ground:
#3 (E158) No. 35 — Engine ground:
#4 (E158) No. 48 — Engine ground:
#4 (E158) No. 47 — Engine ground:
Is the resistance 1 MΩ or
more?
Go to step 84. Repair the short
circuit to ground in
harness between
ECM connector
and fuel injector
connector.
84 CHECK IGNITION SYSTEM.
Check the ignition system. <Ref. to EN(w/o
STI)(diag)-80, IGNITION CONTROL SYSTEM,
Diagnostics for Engine Starting Failure.>
Is the ignition system normal? Go to step 85. Repair the ignition
system. <Ref. to
IG(w/o STI)-2,
General Descrip-
tion.>
85 CHECK FREEZE FRAME DATA.
Using the Subaru Select Monitor, read the val-
ues in «A/C Compressor Signal» and «Idle A/C
load correct».
NOTE:
For detailed operation procedures, refer to “En-
gine Freeze Frame Data Display”. <Ref. to
EN(w/o STI)(diag)-43, DISPLAY OF ENGINE
FREEZE FRAME DATA, OPERATION, Subaru
Select Monitor.>
Does the value of «A/C Com-
pressor Signal» indicate ON
output, and does the value of
«Idle A/C load correct»
increase?
Check the air con-
ditioner. <Ref. to
AC(diag)-12,
INSPECTION,
Diagnostics with
Phenomenon.>
<Ref. to AC(diag)-
2, PROCEDURE,
Basic Diagnostic
Procedure.>
Go to step 86.
86 CHECK FREEZE FRAME DATA.
1) Using the Subaru Select Monitor, read the
value of «Electric Load Feedback Val».
NOTE:
For detailed operation procedures, refer to “En-
gine Freeze Frame Data Display”. <Ref. to
EN(w/o STI)(diag)-43, DISPLAY OF ENGINE
FREEZE FRAME DATA, OPERATION, Subaru
Select Monitor.>
2) Compare the value of «Electric Load Feed-
back Val» with that of «ISC Learning Value»,
which is described in “Engine Current Data Dis-
play”. <Ref. to EN(w/o STI)(diag)-37, DISPLAY
CURRENT ENGINE DATA, OPERATION, Sub-
aru Select Monitor.>
NOTE:
For detailed operation procedures, refer to
“Current Data Display For Engine”. <Ref. to
EN(w/o STI)(diag)-37, DISPLAY CURRENT
ENGINE DATA, OPERATION, Subaru Select
Monitor.>
Is the value of «Electric Load
Feedback Val» 20% or more of
«ISC Learning Value»?
Check the genera-
tor and power
assisted system.
<Ref. to SC(w/o
STI)-45, INSPEC-
TION, Generator.>
<Ref. to PS(diag)-
2, Basic Diagnostic
Procedure.>
Go to step 87.
87 CHECK FREEZE FRAME DATA.
1) Using the Subaru Select Monitor, read the
values of «Vehicle Speed», «Engine Speed»
and «AT turbine speed».
NOTE:
For detailed operation procedures, refer to “En-
gine Freeze Frame Data Display”. <Ref. to
EN(w/o STI)(diag)-43, DISPLAY OF ENGINE
FREEZE FRAME DATA, OPERATION, Subaru
Select Monitor.>
Is there any freeze frame data
indicating that the value of
«Vehicle Speed» is less than 30
km/h (18.6 MPH), and that the
difference in values between
«Engine Speed» and «AT tur-
bine speed» is less than 100
rpm?
Repair the CVT.
<Ref. to
CVT(TR690)-3,
General Descrip-
tion.>
Go to step 88.
